Sunspot AR2661 is growing and with an open sky this morning, I was able to take some pictures in visual aswell in H-alfa. Using my TAL200K f/10 with Astrosolar filter ND5 results in a shutter speed of 1/500s applying ISO100. This resulted in a very sharp picture with a lot of contract and details. Editing was done using CS4.
Near Sunspot AR2661 and seen at the "edge" of the sun, some big prominences could be observed using my PST40. The best result was realized using ISO800 and a shutter speed of1/25s. The picture was taken afocal on a zoom lens 8-24mm on 24mm and finished using CS4.
